There are four common flocculants, can be divided into two categories. Therefore, the first category is a better choice. In addition, although these two are more effective on the follow-up of the RO membrane pollution, flocculant concentration is also an important factor in this process, if directly after the addition of micro-filtration or ultrafiltration: ferric chloride and polyaluminum chloride , Is the home of choice; The second category: aluminum sulfate and cationic polyelectrolyte, both in a wide range of PH value to play a role, and will not follow the RO membrane caused by pollution, but can easily result Sediment, the effect will be better. the first sort
